Description

Technical Field

[0001] This utility model relates to the field of surface coating technology for storage tanks, and in particular to a surface coating device for processing storage tanks. Background Technology

[0002] Storage tanks are containers used to store liquids, gases, or solid materials, and are widely used in industries such as petroleum, chemical, food, and pharmaceuticals. Depending on their purpose and material, storage tanks can be classified as metal tanks (such as carbon steel and stainless steel), plastic tanks, and fiberglass tanks. Their design must consider requirements such as pressure resistance, corrosion resistance, and sealing. However, since storage tanks are mostly placed outdoors during use, a protective coating needs to be applied to the tank surface.

[0003] Most spraying equipment on the market consists of a base, support components, rotating components, clamping components, and spraying components. By installing or hoisting the storage tank onto the base, the rotating components work in conjunction with the clamping components to rotate the storage tank, and then the spraying components perform spraying operations on the surface of the storage tank.

[0004] However, when the spraying equipment is working, the paint is usually sprayed directly onto the surface of the storage tank by a high-pressure nozzle. However, when the paint sprayed by the high-pressure nozzle comes into contact with the surface of the storage tank, a reaction force is generated, which causes some paint to splash and remain in the air, resulting in some paint waste and significant environmental pollution. Utility Model Content

[0005] The purpose of this invention is to solve the problem of paint splashing during the operation of high-pressure nozzles in existing spraying equipment, which leads to waste of raw materials and environmental pollution. Therefore, this invention proposes a surface spraying device for processing storage tanks.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A surface coating device for processing storage tanks includes a mounting base fixedly installed on a support component. The mounting base has a connecting pipe fixedly installed on it, and a feed pipe fixedly installed on the connecting pipe. A plurality of nozzles are arranged equidistantly on the connecting pipe, wherein multiple nozzles are circumferentially and equidistantly installed at the spraying end of each nozzle. Each nozzle has a pressurizing chamber and a connecting chamber connected to the nozzle. Each nozzle has a splash guard fixedly installed to intercept splashed coating material.

[0008] To facilitate the interception of splashed paint, preferably, the anti-splash part includes a mounting ring fixedly installed on the nozzle, on which multiple air nozzles are equidistantly mounted, and a cavity is formed between the mounting ring and the nozzle, with the air nozzles communicating with the cavity.

[0009] In order to form an air wall when the nozzle is working, the angle between the fluid ejected by the nozzle and the axis of the nozzle is further 10 degrees to 15 degrees.

[0010] To facilitate the operation of the jet nozzle, an air inlet pipe is further fixedly installed on the mounting ring, and the air inlet pipe is connected to the cavity inside the mounting ring.

[0011] To facilitate the blocking of some splashed paint, preferably, the angle between the fluid sprayed by the nozzle and the axis of the nozzle is in the range of 15 degrees to 20 degrees.

[0012] To increase the pressure of the nozzle, preferably, the pressurizing chamber is configured as a frustum-shaped chamber, with the large end of the frustum-shaped chamber connected to the connecting pipe and the small end of the frustum-shaped chamber connected to the nozzle orifice of the nozzle.

[0013] To facilitate the entry of external coatings into the connecting pipe, the feed pipe is preferably made of PP material.

[0014] To improve the adaptability of the nozzle, preferably, the nozzle is made of stainless steel.

[0015] Compared with the prior art, the present invention provides a surface spraying device for processing storage tanks, which has the following beneficial effects:

[0016] 1. The surface spraying equipment for processing storage tanks uses multiple nozzles installed on the outside of the connecting pipe and nozzles installed on the nozzles. When the nozzles are working, the paint inside the nozzles is pressurized by the pressurization chamber and then sprayed out by the nozzles. At the same time, paint enters the connecting chamber and is sprayed out through the nozzles. Because the nozzle pressure is different from the nozzle outlet pressure, the tilted nozzles spray the paint onto the surface of the storage tank, causing the paint to be close to the paint at the nozzle outlet, thus intercepting some of the splashed paint, effectively reducing splashed paint, and improving the utilization rate of materials.

[0017] 2. The surface spraying equipment for processing storage tanks, through the anti-splash section, further sprays air through the air nozzles while the nozzle is working. Multiple air nozzles work together to form a cone-shaped air wall around the nozzle, thereby blocking the remaining splashed paint and facilitating use.

[0018] The parts of this device not described herein are the same as or can be implemented using existing technologies. This utility model uses a nozzle and a splash guard in conjunction with the spray head. After the splash guard is working, the air nozzle forms an air wall, which effectively intercepts splashed paint and prevents excessive paint residue from polluting the environment.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Example:

[0027] Reference Figures 1-4A surface coating device for processing storage tanks includes a mounting base 1 fixedly mounted on a support component. A connecting pipe 2 is fixedly mounted on the mounting base 1, and a feed pipe 3 is fixedly mounted on the connecting pipe 2. The feed pipe 3 is a flexible PP material. A plurality of nozzles 4 are evenly arranged on the connecting pipe 2, with the number of nozzles 4 ranging from 4 to 8, preferably 6 in this application. The nozzles 4 are made of stainless steel, such as 904L stainless steel, 316 stainless steel, or 304 stainless steel, for adapting to coatings containing a mixture of various raw materials. The spraying ends of the nozzles 4 are annularly spaced... The nozzle 7 is equipped with multiple nozzles 7, the number of nozzles 7 being set to 3-6, and the preferred number in this application is 4. The angle between the fluid sprayed by the nozzle 7 and the axis of the nozzle 4 is in the range of 15 degrees-20 degrees, and the preferred angle in this application is 20 degrees. When the nozzle 4 is working, some paint enters the connecting cavity 6 and is sprayed out from the nozzle 7, so that the pressure of the paint sprayed out by the nozzle 7 is less than the nozzle pressure of the nozzle 4. Therefore, the paint sprayed out by the nozzle 7 forms an interception zone. The nozzle 4 is provided with a pressurizing cavity 9 and a connecting cavity 6, which are connected to the nozzle 7. A splash guard is fixedly installed on the nozzle 7 to intercept splashed paint.

[0028] Specifically, multiple nozzles 4 installed outside the connecting pipe 2 and nozzles 7 installed on the nozzles 4 work together. When the nozzles 4 are working, the paint inside the nozzles 4 is pressurized by the pressurizing chamber 9 and then sprayed out by the nozzles 4. At the same time, paint enters the connecting chamber 6 and is sprayed out through the nozzles 7. Because the pressure of the nozzles 7 is different from the pressure at the nozzle outlet of the nozzles 4, the tilted nozzles 7 spray the paint onto the surface of the storage tank, causing the paint to stick close to the paint at the nozzle outlet of the nozzles 4, thus intercepting some of the splashed paint, effectively reducing splashed paint, and improving the utilization rate of materials.

[0029] The splash guard includes a mounting ring 5 fixedly mounted on the nozzle 7. Multiple air nozzles 8 are equidistantly mounted on the mounting ring 5. The number of air nozzles 8 is set to 6-12, and the preferred number in this application is 8. The angle between the fluid sprayed by the air nozzles 8 and the axis of the nozzle 4 is in the range of 10 degrees-15 degrees, and the preferred angle in this application is 15 degrees. When the air nozzles 8 work, they spray air, so that multiple air nozzles 8 spray air simultaneously to form an air wall to block the splashed paint. A cavity is formed between the mounting ring 5 and the nozzle 4 to form a pressurization zone to increase the spray pressure of the air nozzles 8. An air inlet pipe 10 is fixedly mounted on the mounting ring 5 and is connected to the inner cavity of the mounting ring 5 for external equipment to inject air into the mounting ring 5.

[0030] Specifically, through the splash guard, when the nozzle 4 is working, air is further ejected through the air nozzle 8. Multiple air nozzles 8 work together to form a cone-shaped air wall around the nozzle 4, thereby blocking the remaining splashed paint and making it convenient to use.

[0031] The pressurizing chamber 9 is configured as a frustum cavity, with the large end of the frustum cavity connected to the connecting pipe 2 and the small end of the frustum cavity connected to the nozzle of the spray head 4, for pressurizing the paint inside the spray head 4.

[0032] In this invention, when the spraying equipment is running and drives the storage tank to rotate, the paint is transferred to the connecting pipe 2 through the feed pipe 3. Furthermore, as the feed pipe 3 continuously supplies paint, the pressure in the connecting pipe 2 increases, and the paint flows into the nozzle 4. Then, the paint is sprayed out through the nozzle through the pressurization chamber 9 provided in the nozzle 4. At the same time as the nozzle 4 is spraying, some paint enters the connecting chamber 6 and is sprayed out through the nozzle 7. Then, the paint sprayed out by the nozzle 7 contacts the tank body close to the center of the nozzle 4, thereby suppressing some of the splashed paint.

[0033] While the nozzle 4 is working, the air inlet pipe 10 transports air to the mounting ring 5 through external equipment. Then, the air pressure inside the mounting ring 5 increases and is discharged through the jet nozzles 8. Subsequently, the eight jet nozzles 8 work together to form an air column, which disrupts the airflow inside the nozzle 4. This causes the splashed paint to re-adhere to the surface of the storage tank along with the air discharged from the jet nozzles 8, effectively suppressing splashed paint and improving the utilization rate of the paint.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
